HDTV stands for high-definition television. HDTV is the solution in theory, it has higher resolution, providing a sharper, crisper, clearer picture.

HDTV Knowledge:

The fact that a product bears the label "HD ready" does not necessarily mean that it can display the full picture resolution possible from a HD source. Most HD-ready sets do not have enough pixels (1920x1080 or 1280x720) to give true pixel-for-pixel representation without interpolation of higher HD resolutions.

Theoretically, even pixel-for-pixel is not enough, as sampling theory shows that proper image reconstruction requires more pixels in the display than were used for the original picture. This is why SDTV video sources (especially DVD) look much better on a HDTV than on the best SDTV (this is a consequence of basic sampling theory, and not a matter of image enhancement).

The term HD compatible is also being used in the UK to indicate that a display device has HDMI capability but with lower than HD-ready resolution.

HDTV is capable of "theater-quality" audio because it uses the Dolby Digital (AC-3) format to support "5.1" surround sound.

The pixel aspect ratio of native HD signals is 1.0, or 1 pixel length = 1 pixel width. New HD compression and recording formats such as HDV use rectangular pixels for more efficient compression and to open HDTV acquisition for the consumer market.

Its ideal the antenna for with who want to complement their satellite or cable installations consumers added HDTV reception capability." -
